HANBit HMS51232J4 SRAM MODULE 2Mbyte (512K x 32-Bit), 68-Pin JLCC Packaging Part No. HMS51232J4 GENERAL DESCRIPTION The HMS51232J4 is a static random access memory (SRAM) module containing 524,288 words organized in a x32-bit configuration. The module consists of four 512K x 8 SRAMs mounted on a 68-pin, single-sided, FR4-printed circuit board. Four chip enable inputs, (/CE1, /CE2, /CE3 and /CE4) are used to enable the module’s 4 bytes independently. Output enable(/OE) and write enable(/WE) can set the memory input and output. Data is written into the SRAM memory when write enable (/WE) and chip enable (/CE) inputs are both LOW. accomplished when /WE remains HIGH and /CE and output enable (/OE) are LOW. For reliability, this SRAM module is designed as multiple power and ground pin. All module components may be powered from a single +5V DC power supply and all inputs and outputs are fully TTL-compatible. Reading is FEATURES w Access time : 10, 12 and 15ns w High-density 2MByte design w High-reliability, low-power design w Single +5V ±0.5V power supply w Three state output and TTL-compatible w FR4-PCB design w Low profile 68-Pin JLCC PIN ASSIGNMENT DQ 1 6 A1 8 A1 7 / CE 4 / CE 3 / CE 2 / CE 1 NC V cc NC NC / OE / WE A1 6 A1 5 A1 4 DQ 1 5 DQ17 DQ18 DQ19 Vss DQ20 DQ21 DQ22 DQ23 Vcc DQ24 DQ25 DQ26 DQ27 Vss DQ28 DQ29 DQ30 10 9 8 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 7 6 5 4 3 2 1 68 67 66 65 64 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 26 44 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 OPTIONS w Timing 10ns access 12ns access 15ns access w Packages 68-pin JLCC MARKING -10 -12 -15 J URL: www.hbe.co.kr Rev. 1.0 (September / 2002) 1 DQ 3 1 A6 A5 A4 A3 A2 A1 A0 V cc A1 3 A1 2 A1 1 A1 0 A9 A8 A7 DQ 0 HANBit Electronics Co.,Ltd. 68-Pin JLCC TOP VIEW DQ14 DQ13 DQ12 Vss DQ11 DQ10 DQ9 DQ8 Vcc DQ7 DQ6 DQ5 DQ4 Vss DQ3 DQ2 DQ1 HANBit PIN DESCRIPTION DQ0 – DQ31 A0 – A18 /WE /CE1-4 /OE Vcc Vss Data Inputs/Outputs Address Inputs Write Enable Chip Selects Output Enable Power Supply Ground HMS51232J4 BLOCK DIAGRAM /CE1 /WE /OE A0-18 /CE2 /CE3 /CE4 U1 512Kx8 U2 512Kx8 U3 512Kx8 U4 512Kx8 8 8 8 8 DQ0-7 DQ8-15 DQ16-23 DQ24-31 TRUTH TABLE MODE STANDBY NOT SELECTED READ WRITE /OE X H L X /CE H L L L /WE X H H L DQ HIGH-Z HIGH-Z Dout Din POWER STANDBY ACTIVE ACTIVE ACTIVE URL: www.hbe.co.kr Rev. 1.0 (September / 2002) 2 HANBit Electronics Co.,Ltd.
